The Longest Day Of The Year

After nearly walking away from the sport earlier this year, Utah’s own Keegan Swenson roared back in Switzerland to claim the rainbow jersey. The 31-year-old became the first American man to win the UCI Marathon Mountain Bike World Championship, grinding through 125 kilometers and 5,000 meters of brutal alpine terrain. Powered by grit, redemption, and a set of Tannus Tubeless Inserts, Keegan now carries the title of 2025 UCI Marathon World Champion.

Keegan Swenson proved once again why he’s the rider to beat at the Leadville Trail 100 MTB, securing his fifth consecutive win with a gritty ride through high-altitude climbs, dusty descents, and relentless headwinds. Racing at over 10,000 feet, Swenson leaned on his discipline, determination, and a not-so-secret weapon, Tannus inserts, to push through where flats or fatigue could have ended the day. From the Utah connection that first brought him to Tannus, to the lessons learned in past races, Keegan’s story is one of endurance, smart gear choices, and respect for the legends who came before him.
